He could have replaced the Angular code with Ember code and levied the exact same complaints. Re-read the article and try to figure out which complaints aren't also valid for other large JS frameworks. It's clear he's a libraries > frameworks guy, which is a perfectly valid viewpoint to have, but it's cowardly to frame such a debate as a thoughtful criticism of a specific framework because it won't draw rebuttals from nearly as many people who might otherwise feel the need to chime in.
He specifically mentions performance many times but has no statistics to back this up. I have created a web app with Angular and it runs fine on old Android phones and iPhones. We don't see any performance problems. Of course YMMV but he/she makes it should like the performance is a really big problem that everyone will get affected by which I thinks is wrong, most apps won't have any major performance problems.
